I am using "Color by expression" but the graphics are gray

Hi,

Please help me:

I am using "Color by expression" but the graphics are gray

The Dimension:

=if((DRIVERTIME < 341),'LOW',

    if((DRIVERTIME >= 341) And (DRIVERTIME < 361),'MEDIUM',

        if((DRIVERTIME >= 361),'HIGH')))

The Measure:

=Count(TRIPS)

Color by expression:

=if((DRIVERTIME < 341),Green(),

    if((DRIVERTIME >= 341) And (DRIVERTIME < 361),Yellow(),

        if((DRIVERTIME >= 361),Red())))

THANKS!!

I would suggest finding the RGB value of the colour and using that e.g.

if("Gender"='Male',rgb(68,119,170),if("Gender"='Female',rgb(204,102,119), rgb(253,219,102)))

Bella, thanks

I also tried that option, but it does not work either

Because the color expression is calculating over multiple rows, you must do some sort of aggregation over DRIVERTIME. As you have it now in the IF(), DRIVERTIME will return null when there are multiple rows. Try using "Avg(DRIVERTIME)" in your color expression.

Please check if this might be the reason.

Are you using alternative dimension?
